To all whom it mac concern:

Be it known that Lldnvnn VLAS, a subject of the Queen of Holland, residng at Paterson, in the county of Passaic andState of New Jersey, haveinvented certain new and useful Improvements in Carpenters Implements,of which the following is a specification.

This invention relates to the art ofindieating the plane of cutting arafter 'or the like so that the face left by the cutting will abut fiatagainst another rafter or the like to which the first rafter is to bejoined, and it has reference particularly to that branch of this artwhich is concerned with indicating the plane of cutting where such planeis perpendicular to no side of the rafter, as in the case of the hip,valley, jack and cripple rafters of a roof. The carpenter, knowing therun and rise of a roof, can by of the scale provided on certaincarpentefis squares determine theangle of cut for an inclined. rafterwhose end is to abut another rafter face to face and which stands in theplan at right angles thereto; but when the thus inclined rafter standsin the plan oblique to the other rafter he has to depend on certaincalculations which ordinary carpenters are unable and which in any eventare more or less tedious to perform. The object of this invention,therefore, is to provide an implement whereby a line such as theplumb-cut being found, the line complementary thereto to represent theplane of cut may be easily determined.

The invention broadly consists in pair of rules pivoted together so thateach is confined to move in a definite plane and gaging means on onemember adjustable toward and from the plane of movement of.

the latter. For facility of description ll have designated the memberhaving the gaging means as the body member and the other as theauxiliary member.

In the drawings,

Figure 1 is a perspective view of the implement;

Figure 2 is a side elevation thereof;

Figure 3 is a sectional view on line 3-3 Figure 2; a

Figure 4c shows an architects or builders plan of the valley portion ofa roof frame; and

Figure 5 shows a rafter and the plumbout thereon and, in dotted outline,my implement in position for indicating the line complementary to theplini'ibcut.

The body member is shown as a rule it having an edge beveled oif at theback, at 7). At one end of this member is a screw bolt 0 arranged in aplane perpendicular "thereto and forming a pivot, and on this pivot isconfined to move in a plane parallel to the member a the auxiliarymember (Z. The member (2 may be secured in any angular relation to themember a by tightening the screw bolt; the member may hav r.longitudinal slot (Z to receive the screw bolt, whereby member d mayalso be adjusted longitudinally, as in certain cases will be foundconvenient.

' The member a; has a pair of transverse tr angular guides projectingfrom its front face, perpendicular thereto; grooves e in the adjoiningfaces of these guides and a. longitudinalslot f in the member a receivea tongue 9 which forms the aforesaid gaging means. This tongue is a fiatplate, and since the ways 6' are perpendicularto the member a said.tongue stands in aplane pen pendicular to and extending longitudinallyof said member and is shiftablc in said plane so that its working edge ymay a. ume different distances from the bacl r. of 1 .ember a,

The lower end of the member a, as shown in Figi-s. l and 2 l desigmiteits basai end; in the present case it is formed by the outer or lowerface of the lower guidec, which isperpendicular to the plane of membero.At the, rear end of the tongue its lower edge has a lug g which projectsinto coincidence with the plane of said face of the lower guide 0 (seeFig. 2).

The tongue or gage 9 may be held where adjusted by the set-screw 17b-The implement is used thus: Let a represent the alreadyascertainedplumb-cut line found on a timber A, Fig. 5, which is to form the rafterA (shown also by the builders drawing represented in Fig. 4;) that is tobe joined to the valley rafter B. The gage or tongue 9 is set in membera so that the plane in which its rear edge and the edge (5 of member alie forms a predetermined angle (see 3) with the plane of member a (or,which is the same thing, with the plane of movement of member (Zrelatively to a). This angle is determined from the builders drawing(Fig. 4) by setting the implement basal end down on the drawing in theangle between the two raftthe lines representing adjoining faces of thetwo rafters; the lug g assists in truing of joints appear.

the implement at this time to a perpendicular relation to the drawing.The implement 1 is then transferred to the actual timber (Fig. 5) andplaced with the edge 7) of member a true to the plumb-cut w and thecorresponding edge of member at ex tending across an adjoining face ofthe time ber, and a line is marked, as at y, on the latter face alongthe edge of member d. The lines :0 and y will represent a plane, andwhatever the angularity of the plumbcut line relatively tothe timberthis plane will be perfectly vertical or plumb when the rafter A is inplace; that is, the end formed on said rafter in said plane willsquarely abut the side of the valley rafter B. It will be seen that whenthe angle is determined as in Fig. 4, it fixes 'the angular positionwhich member a will occupy when placed against the actual timber, andthat that in turn fixes the plane in which the member cl movesin short,the plane of the cut. The carpenter may apply the imple ment to the sameside of the actual timber as it is shown as occupying in connection withthe illustration of said timber afforded by Fig. 4-, that is, the innerside; but a timber is usually sawed from near the end inward Fig. 5.shows the implement adapted to the outer side, the plane of the out notbeing altered because it will be apparent that the implement is in Fig.5 reversed relatively to its position in Fig. 4 and abuts the oppositeside of the timber.

To simplify the explanation I have here inbefore referred to but oneedge Z). Both edges, 6 as well as Z), of member a will usually bebeveled and be working edges,

and correspondingly both of the edges of" .planes for cuts whose apicesare at either the right or left sides of timbers. Fig. 4 showstheimplement on the builders drawing at points where several differentkinds The bottom; surfaces of the lower guide 6 and the 111 g, being ina plane perpendicular to t e member a, afford rests for the implementwhen placed on the drawing (Fig. 4) and thus insure accuracy indetermining the adjustment of the gage 9.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is 1. In an implement for use in indicatingthe plane of cutting a timber cross-wise, the combination of a pairofrules pivoted together so that each is confined to move in a definiteplane, and a gaging device connected with one rule to move rectilinearlytoward and from the plane of movement" thereof.
